Also having this issue
Running Windows 7 Home Premium
Direct X 11
10 G Ram
3.4 Ghz AMD processor 64 bit
ATI HD 5770 dual link graphics - 60hz seems to be the only rate available.
2 HP HPS 2331 monitors.
I get the same exact scenario as described here. The menu shows up. when play is pressed, the NWN logo splash screen appears and then it shuts down.
I have also tried running in nearly all compatibility modes, with and without running as administrator, also at various different resolutions. Installed patch 1.69, etc.
Here is the error that appears on the event log for it.
